(A) Measurements, tests, and analyses of the characteristics of wastewater to which reference is made in this chapter, shall be determined in accordance with 40 CFR 136 methods approved by the Manager, and shall comply with state and federal law. Sampling locations, times, durations, and frequencies shall be determined on an individual basis, subject to approval by the Manager. The user shall have the option to use, at the user's own expense, more completely approved sampling methods, locations, times, durations, and frequencies than specified by the Manager. Any additional results beyond those required by the Commission are also to be reported to the Commission.
(B) Measurements, tests, and analyses of the characteristics of wastewater required by this chapter shall be performed by a qualified laboratory. When such analyses are required of a user, the user shall make arrangements with a qualified laboratory, which may include that of the user, to perform such analyses.
(C) Monitoring of wastewater characteristics for any purpose shall be conducted on a frequency deemed necessary by the Manager, unless more frequent monitoring is required by authority other than this chapter.
(D) Upon demonstration by any person that the characteristics of the wastewater discharged by that person are consistent, the Manager may reduce the monitoring frequency as may be required by authority other than this chapter. In no case shall the frequency of monitoring be less than semiannual for determining compliance with federal, state, or Commission pretreatment standards.
(E) In determining the discharge characteristics, factors such as continuous, batch, or seasonal operation, as well as the information requirements of other provisions in this chapter, shall be considered by the Manager. The Manager may obtain wastewater samples as required to verify the consistency of discharge characteristics.
(F) Fees for any given measurement, test, or analysis of wastewater required by this chapter and performed by the Commission shall be the same for all users, regardless of the quantity or quality of the discharge, and shall reflect only direct cost. Costs of analyses performed by an independent laboratory at the option of the user shall be borne directly by the user.
